Assessment Guidance
Guidance for achieving higher grades
- 💡Memorise the colour wheel and be able to explain how complementary colours neutralise each other.
- 💡Always structure your answers to include the consultation, preparation, application, and aftercare stages.
- 💡Use technical terminology correctly, such as 'underlying pigment', 'porosity', and 'colour removal'.
- 💡In practical assessments, demonstrate a methodical approach and adhere to health and safety regulations at all times.
- 💡Always justify your choices in practical assessments. For example, explain why you selected a specific cutting angle or colour formula based on the client's hair condition and desired outcome.
- 💡In written exams, use industry terminology correctly (e.g., 'graduation' vs. 'layering') and link your answers to health and safety protocols to show comprehensive understanding.
- 💡Practice time management during assessments. Allocate time for consultation, preparation, and cleanup, and demonstrate efficiency without compromising quality.
Common Mistakes
Common errors to avoid in your coursework
- Failing to perform a strand test before the full application, leading to unexpected colour results.
- Misidentifying the underlying pigment, resulting in an incorrect neutralisation and an undesirable final colour.
- Overlapping colour onto previously coloured hair, causing banding or uneven colour.
- Not considering the hair's porosity, which can lead to uneven colour uptake and patchiness.
- Misconception: Colour correction is just applying more dye. Correction: It requires removing pigment, using fillers, and sometimes multiple sessions to avoid damage and achieve the desired shade.
- Misconception: Advanced cutting is only about complex shapes. Correction: It also involves adapting techniques to hair density, texture, and growth patterns, not just following a template.
- Misconception: Salon management is just about scheduling. Correction: It includes financial planning, marketing, staff training, and compliance with health regulations.
